Production methods

After the grapes destined for Vin Santo are harvested in September or October, they are laid out on straw mats, often under rafters or staircases. They are kept in warm, well ventilated rooms that allow the moisture in the grape to evaporate. This process of desiccation

 known as a madre that includes a small amount of finished Vin Santo from previous years production. It is believed that this older wine can help jump start the fermentation process and also add complexity to the wine.

 or air space would emerge in the barrel and oxidation took place. This gave the wine its characteristic amber color but also flavors and traits that may be characterized as wine faults. Towards the end of the 20th century, more produces began switching to oak barrels while maintaining the tradition of not topping up the barrels and filling in the ullage space. This angel's share still produces some level of oxidation, though not as severe as the style was historically made. Modern winemaking technique also calls for more temperature control and keeping the wine in rooms with a consistent temperature that promotes more fresh flavors in the wine and fewer faults.

Some producers will still use non-oak barrels, such as chestnut, juniper

 region use different wood types to add complexity to their vinegar. As a fall back, if their wines become too oxidized or do not develop the way the producer wishes, some Vin Santo may be intentionally converted into vinegar that is very desirable in the culinary market.

Wine styles

The styles, color, sweetness and quality of Vin Santo can vary widely depending on the grape varieties and production methods used to make the wine. While white grapes, such as Trebbiano and Malvasia in Tuscany, are most widely used, red grape varieties (such as Sangiovese) can be used to produce a rosé style wine. When red grape varieties are used, the wine is often labeled as a Occhio di Pernice or "eye of the partridge," which has its own DOC classification in several regions of Italy. The wines can be made to fit any style of sweetness levels from bone dry, almost Fino Sherry-like, to extremely sweet and on par with the botrytized wines of France and Germany. The wines can even be fortified with grape spirit like Port added during fermentation. These fortified examples are usually labelled as Vin Santo Liquoroso.

The color of wine Vin Santo can range from a pale to dark amber to even neon orange. The flavors typical of Vin Santo often include nutty or raisin

Wine regions

For most of the 20th century, Vin Santo was often sold as basic vino da tavola due to Italian wine authorities' difficulties in classifying the many different styles of the wine. Today most of the major Italian wine producing regions have their own DOCs for specific Vin Santo wines produced in those areas. While the style is traditionally associated with Tuscany, examples can be found on the international wine market from throughout Italy. In the Trentino region, a dried straw wine made from the Nosiola grape is popularly labeled as Vino Santo. A noticeable difference between the Trentino and Tuscan examples is that the Trentino wines are usually less oxidized due to the wines regularly being "topped up" to prevent a large ullage.

There are three distinct styles of Vin Santo that can produced under the Colli dell'Etruria Centrale DOC label-Occhio di Pernice, Abboccato and Amabile (also known as Secco). The first style, Occhio di Pernice, is a pale rosé style wine made from at least 50% Sangiovese with a mix of local red and white grape varieties permitted to fill in the remaining 50%.
